Correct Answer - Option 3 : Rs. 1000
Given:
1st Discount = 25% of M.P
2nd Discount = 20% of 1st Discount
S.P = Rs. 600
Concept Used:
D = M.P × Rate of Discount
Successive Discount = [a + b - (ab/100)]%
M.P = Marked Price, D = Discount, S.P = Selling Price
Calculation:
Let the marked price be x.
According to the question,
x × (75/100) × (80/100) = 600
⇒ x = (600 × 100 × 100)/(75 × 80)
⇒ x = 1000
∴ The Marked Price is Rs. 1000.
